Impregnated carbon adsorbents for the removal of mercury from liquid hydrocarbons are used in a variety of applications. The activated carbon impregnated adsorbents in the present invention remain effective in removing mercury. Generally, these activated carbons are comprised of an activated carbon adsorbent impregnated with a composition containing metal halide or other reducing halide, supplemented according to the desired characteristics with other elements. The formulation of the impregnants in the present invention can be varied to adjust the performance characteristics so as to meet the desired mercury removal performance criteria, to achieve enhanced removal of organic bound mercury from liquid hydrocarbon, and to have other advantages useful in a variety of applications. These impregnated carbon adsorbents possess desirable qualities regarding their ability to remove even trace levels of mercury from liquid hydrocarbon without a leaching effect of the impregnants used.

The method for removing mercury from a flue gas stream of the present invention is comprised of first treating a sorbent with a metal halide, and then contacting a sufficient amount of the sorbent with a gas stream for a sufficient amount of time to bind with a desired amount of the mercury in said gas stream. The metal is selected from Groups I and II of the periodic table of the elements. The halide is selected from the group consisting of I, Br, Cl. The metal halide comprises from about 0.5% to 25% by weight of said treated sorbent.
